Metrocide: A Tale Of Sixty Cities

via Torontoist by David Topping on 7/24/08

Is Toronto a dangerous city? And is it getting worse? This week for Metrocide, Torontoist is examining a sea of homicide data and trying to come up with conclusions based not in fear or fantasy but fact.

Ever since Toronto earned its reputation as a safe city, safe has tended to be a relative term—safe compared to Detroit, safe compared to New York, safe compared to Chicago. Comparisons between individual cities' crime rates are at once useful and flawed; while they help contextualize a city by putting it into dialogue with others, they also "provide no insight into the many variables that mold the crime in a particular town, city, county, state, region, or other jurisdiction" (so says the FBI). But insofar as they measure the effects of crime, rather than their causes, city-to-city comparisons are a good basis for determining relative safety, and—especially when it comes to homicide rates—play a large role in shaping public perception.

Today, we'll look at how Toronto's recent homicide rates stand up to thirty-four American cities and twenty-seven Canadian ones.

A Note on Statistics

Today, we're comparing Toronto to American and Canadian cities only. Not that we wouldn't like to toss worldwide cities into the mix, of course, but there are some problems with doing so. No over-arching body (say, the United Nations) seems to have homicide data for individual cities (rather than (whole countries) measured in any consistent way. Second, if we researched cities on an individual basis (say, picked twenty large European cities based on size), it is unlikely that each would measure homicides and homicide rates the same way as every other city or country did. (Would negligent manslaughter count in the numbers? Would non-negligent manslaughter? Infanticide? Will they provide rates, or just numbers? And if it's just numbers, will they provide a population that the rate can be determined from?) Geography is an issue, too: as we've shown in the past two days, homicide rates change for Toronto depending on what you define "Toronto" as. At this point, thus, accurately comparing worldwide cities is unfortunately beyond the scope of this week's project.

Fortunately, Statistics Canada and the FBI do make good statistical bedfellows; so far as we can see, their data measures cities in the same way for determining the same data. So: how does Toronto's homicide rate compare to American cities'?

Extraordinarily well; Toronto's numbers absolutely pale in comparison to American cities. Its metropolitan homicide rate in 2006 was lower than every American city with a population above 500,000 (charted above). And of the seventy-two American cities with populations over 250,000, Toronto's 2006 metropolitan homicide rate (1.8 per 100,000) was lower than every other city except for Plano, Texas—the wealthiest city in the United States—which had a homicide rate of 1.6 per 100,000.

In Canada, the picture is different. (Do note the change in scale from the American cities chart, and that this chart lists 2007 homicide rates.) Canadian cities, overall, do quite well in comparison to American ones in terms of homicide rate, regardless of geographical proximity; in 2006, Windsor's homicide rate (1.5) was thirty-one times smaller than Detroit's, and in the same year, Toronto's homicide rate (1.8) was fourteen times smaller than Buffalo's.

But, as we noted in March, and as was widely-reported last week, Toronto still holds its own against other Canadian cities. Of the twenty-six Canadian cities with a Central Metropolitan Area (CMA) population above 100,000 (charted above), Toronto's homicide rate in 2007 (2.0) ranked ninth highest, tied with Saint John. Of the nine cities in Canada with a CMA population above 500,000, Toronto's homicide rate in 2007 ranked fifth highest—with a lower rate than Winnipeg, Edmonton, Calgary, Vancouver—and is not far from Montreal, Hamilton, and Ottawa's rates (for all three, 1.6 homicides per 100,000). No large city in Canada had as good of a year for homicides as Quebec City had in 2007: of a population of about 750,000, it had no homicides whatsoever. Even if that was in part the result of good fortune—the last year it hadn't had a homicide before 2007 was 1962, its violent crime rate is similar to Toronto's, and it will unfortunately not be able to repeat the feat this year—the Québec capital consistently has a homicide rate that is on the low end of Canada's larger cities.
